Abstract:
     The invention is related to extraction process of natural iron oxide red which is inorganic pigment. The compounding process of Fe2O3 is given up in the invention, while the natural iron oxide red ore in Qinggou, Hunjiang, Jilin provence which containing too much phosphorus to smelt is used as material to produce the natural iron oxide red (Fe2O3.SiO2.H2O) with non-chemical technique.
